According to Cointelegraph, Lufthansa, one of Europe's largest airline groups, has introduced its nonfungible token (NFT) loyalty program on the Polygon Network. The program enables passengers to convert their trips into NFTs that can unlock rewards such as miles and business lounge vouchers. On August 31, Lufthansa announced the Uptrip mobile application, a project developed by Lufthansa Innovation Hub, the airline group's digital innovation unit, and Miles & More, the airlines' frequent flyer program. Passengers can scan their boarding passes using the app and exchange them for NFT trading cards. Users must connect their crypto wallets within the app to mint and transfer their Uptrip NFTs. Once passengers complete specific NFT collections, they become eligible for rewards like flight upgrades, airport lounge access, frequent flyer status, or award miles. The announcement revealed that there are over 20,000 sign-ups and 200,000 NFT trading cards minted. Lufthansa has previously expressed interest in integrating Web3 technologies into its business, and other airline industry players have also announced plans to implement Web3 in their operations.
